Implementation Reference

• src/f1_mcp_server/f1_data.py:108-141 (handler)

  Core handler function that implements the get_event_schedule tool logic: validates year, fetches schedule from fastf1, serializes data to JSON-compatible format, and returns structured response.
  def get_event_schedule(year: Any) -> dict[str, Any]: """ Get the event schedule for a specified Formula One season. Args: year (int or str): The year of the F1 season Returns: dict: Status and schedule data or error information """ try: # Validate year year_int = validate_year(year) logger.debug(f"Fetching event schedule for {year_int}") schedule = fastf1.get_event_schedule(year_int) # Convert DataFrame to JSON serializable format result = [] for _, row in schedule.iterrows(): event_dict = row.to_dict() # Clean and convert non-serializable values clean_dict = {k: json_serial(v) for k, v in event_dict.items()} result.append(clean_dict) logger.info(f"Successfully retrieved {len(result)} events for {year_int}") return {"status": "success", "data": result} except Exception as e: logger.error(f"Error retrieving event schedule: {str(e)}", exc_info=True) return { "status": "error", "message": f"Failed to retrieve event schedule: {str(e)}", }
• src/f1_mcp_server/server.py:284-296 (registration)

  MCP tool registration in the server's list_tools() method, including name, description, and input schema.
  types.Tool( name="get_event_schedule", description=("Get Formula One race calendar for a specific season"), inputSchema={ "type": "object", "properties": { "year": { "type": "number", "description": "Season year (e.g., 2023)", }, }, "required": ["year"], },
• src/f1_mcp_server/server.py:288-296 (schema)

  Input schema definition for the get_event_schedule tool, specifying required 'year' parameter as number.
  "type": "object", "properties": { "year": { "type": "number", "description": "Season year (e.g., 2023)", }, }, "required": ["year"], },
• src/f1_mcp_server/server.py:161-164 (handler)

  Dispatch handler in the MCP server's call_tool method that routes to get_event_schedule with sanitized arguments.
  if name == "get_event_schedule": if "year" not in sanitized_args: sanitized_args["year"] = int(arguments["year"]) result = get_event_schedule(sanitized_args["year"])
• src/f1_mcp_server/f1_data.py:84-106 (helper)

  Helper function used by get_event_schedule to validate and normalize the year input parameter.
  def validate_year(year: Any) -> int: """ Validate that the provided year is valid for F1 data. Args: year: Year value to validate Returns: Valid year as integer Raises: ValueError: If year is invalid """ try: year_int = int(year) # F1 started in 1950 and we don't want future years far ahead current_year = datetime.now().year if year_int < 1950 or year_int > current_year + 1: raise ValueError(f"Year must be between 1950 and {current_year + 1}") return year_int except (ValueError, TypeError) as e: raise ValueError(f"Invalid year format: {year}") from e
